PetscLogAllBegin

 Turns on extensive logging of objects and events. Logs all events. This creates large log files and slows the program down.

Synopsis

#include "petscsys.h"   
PetscErrorCode  PetscLogAllBegin(void)
Logically Collective on PETSC_COMM_WORLD

Options Database Keys

-log_all -Prints extensive log information

Usage

     PetscInitialize(...);
     PetscLogAllBegin();
     ... code ...
     PetscLogDump(filename);
     PetscFinalize();

Notes

A related routine is PetscLogDefaultBegin() (with the options key -log), which is intended for production runs since it logs only flop rates and object creation (and shouldn't significantly slow the programs).

Keywords

log, all, begin
